Description

Technology Field

[0001] The present invention relates to a wire connecting device, and more specifically, to a wire connecting device that ensures greater safety and workability during wire connection operations, such as connecting broken wires or connecting new wires. Background Technology

[0002] Generally, various types of electrical wires are used for electricity in all buildings and various external devices. These wires are sometimes stripped to make new connections, and are also reconnected to replace them when the insulation is stripped or the wire breaks due to external factors.

[0003] In this way, to make a new connection between wires, a commonly used method involves stripping the insulation from the ends of the wires to be connected, connecting the wires inside the stripped insulation, and then wrapping the connection point with insulating tape.

[0004] In addition, recently, methods are being used to connect and cover wires with stripped insulation by utilizing heat-reducing protective cables in the form of heat-shrinkable tubes or various types of connection terminal cables.

[0005] These various wire connection methods require the user to touch the stripped wires with their hands, so if the work is performed without the power switch being turned off, the worker may be exposed to the risk of electric shock.

[0006] Particularly at construction sites, problems may arise regarding the adhesive strength of insulation tape, heat shrink tubing, or connection terminal cables even after the wires are connected. Furthermore, if the seal is not complete, issues such as water leakage may occur, leading to exposure to the risk of electrical leakage and subsequent electric shock accidents caused by moisture or water.

[0007] To solve these problems, technical content as described in the patent documents specified below has been proposed.

[0008] The core content of the following patent document 1 is to solve safety accidents and electrical leakage problems caused by leakage that may occur when stripping the insulation of a wire, connecting a copper wire, and then applying tape. Referring to Figure 1 of the document, in the wire connection and branching operation, the upper member, consisting of an upper cover, an upper rubber plate (15), and a wire connection plate (17), is pressed with strong force against the wire placed on the lower member, consisting of a lower rubber plate (25) and a lower cover (20), so that the connecting pin (18) of the wire connection plate (17) penetrates the wire and is fixed in the pin hole (28) of the lower cover (20), and the upper and lower rubber plates are configured to be in strong contact with each other.

[0009] However, in the case of Patent Document 1, rainwater seeps in through the gap between the upper cover (1) and the lower cover (2), causing a short circuit. Also, as the original wire is wrapped by the upper cover (1) and the lower cover (2), it takes on a shape different from the original wire and loses the flexibility of the wire.

[0010] As a result, there is a problem in that the flexibility of the original wire is lost at the connection point. In addition, regarding the wire at the entry point of the connection device, due to the shape of the wire connection device, there is a possibility that the wire may break again due to factors acting inside or outside the entry point during use, such as repeated bending of the wire at the entry point connection point.

[0011] Therefore, there is a need for a wire connection device that can ensure flexibility when connecting wires, ensure worker safety and reliability of the wire connection, enable multiple wires to be connected in parallel, and ensure their stability. Prior art literature

[0013] The technical problem that the present invention aims to solve is to provide a wire connection device that allows for convenient connection of wires without the risk of electric shock, facilitates electrical connection of wires, prevents leakage current caused by water or moisture by preventing the insulated wires from being exposed to the outside after electrical connection, improves the appearance by forming the connection part between wires similar to the shape of the wires, and prevents damage to the connection part of the wires due to external factors.

[0046] Hereinafter, the configuration of a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0047] FIG. 1 is a schematic exploded perspective view of a wire connection device (10) before assembly according to one embodiment of the present invention.

[0048] FIG. 2 is an exploded perspective view of a wire connection device (10) according to one embodiment of the present invention.

[0049] FIG. 3 is a schematic longitudinal cross-sectional view of a wire connection device (10) according to one embodiment of the present invention.

[0050] Referring to FIGS. 1 to 3, a wire connection device (10) according to one embodiment of the present invention may include a wire connector housing (100) that electrically connects the ends of different wires through one end and the other end.

[0051] A wire connector housing (100) may be provided to electrically and safely connect the stripped covering areas of different wires, for example, a first wire (11) and a second wire (12), that are inserted in both directions.

[0052] The wire connector housing (100) is provided by combining a rotary connection part (110) including two rotary members (111, 112) and a wire cover part (120).

[0053] A rotating connection part (110) including two rotating members (111, 112) and a wire cover part (120) may each have a structure in which they are separated into upper and lower sections and combined. For example, a wire connector housing (100) may be provided by combining two rotating members separated into upper and lower sections and one wire cover part (120) separated into upper and lower sections. Looking at this as another structure, the wire connector housing (100) may be formed in a combined shape of an upper member (102) including upper rotating members (111b, 111d, 112b, 112d) and upper wire cover parts (122b, 121b), and a lower member (101) including lower rotating members (111a, 111c, 112a, 112c) and lower wire cover parts (122a, 121a).

[0058] The upper member (102) can be coupled to the upper part of the lower member (101) to form a wire connector housing (100) of a wire connection device (10) that connects two different wires (11, 12). The upper member (102) may be provided with a second seating portion (a semicircular tunnel shape at the top corresponding to the first seating hole (110a) and the second seating hole (110b)) that penetrates from one end of the upper member (102) to the other end. The second seating portion is provided at a position corresponding to the first seating portion. When the upper member (102) is coupled with the lower member (101), the first seating portion and the second seating portion may form a single seating hole (110a, 110b) shape to form a storage portion that accommodates the first wire (11) and the second wire (12).

[0059] The end of the first wire (11) and the end of the second wire (12) are seated in the first seating hole (110a) and the second seating hole (110b), and the covering area of ​​the end of the first wire (11) and the covering area of ​​the end of the second wire (12) may be provided to be electrically connected to each other while overlapping with each other in the first seating hole (110a) and the second seating hole (110b).

[0061] A wire connector housing (100) formed by the combination of a lower member (101) and an upper member (102) may include a rotating connection part (110) and a wire cover part (120), and may include various configurations described below.

[0062] The rotating connection part (110) may be positioned between the inner side of the wire cover part (120) described later and between different wires. The rotating connection part (110) may be provided adjacent to each other in both directions to wrap around the first wire (11) and the second wire (12) located in both directions. The rotating connection part (110) may be provided to rotate in different directions to implement the twisting of the sheaths of the first wire (11) and the second wire (12).

[0063] The rotating connection part (110) may include wire connecting members (111a, 111b, 112a, 112b) and rotating cover members (111c, 111d, 112c, 112d). The wire connecting member (111a, 111b, 112a, 112b) can be formed by combining the upper wire connecting member (111a, 111b) and the lower wire connecting member (112a, 112b), which are separated into upper and lower parts, to form a single wire connecting member (111a, 111b, 112a, 112b), and the rotating cover member (111c, 111d, 112c, 112d) can be formed by combining the upper rotating cover member (111c, 111d) and the lower rotating cover member (112c, 112d), which are separated into upper and lower parts, to form a single rotating cover member (111c, 111d, 112c, 112d). The specific structure or configuration of the rotary connection part (110) may be specifically described in the description of the rotary connection part (110) including the first rotary member (111) and the second rotary member (112) described later.

[0064] The wire cover portion (120) is provided on the outer surface of the rotating connection portion (110) to cover the rotating connection portion (110) and form the outer surface of the wire connector housing (100), and may be provided to block the inflow of external foreign matter through the wires connected to each other.

[0065] The wire cover portion (120) may include an outer cover member (121) and a sealing member (122). The outer cover member (121) may be formed by combining upper and lower outer cover members (121) that are separated into upper and lower parts. The sealing member (122) may be formed by combining upper and lower sealing members (122a, 122b) that are separated into upper and lower parts. However, the sealing member (122) may be provided in an injected form depending on its shape or material. The specific configuration or structure of the wire cover portion (120) may be described later.

[0066] The rotational connection part (110) may include a first rotational member (111) and a second rotational member (112) positioned adjacent to each other in the longitudinal direction.

[0067] The first rotating member (111) and the second rotating member (112) may be configured to be coupled while rotating in opposite directions while housing the first wire (11) and the second wire (12). The twisting of the first wire (11) and the second wire (12) located inside is realized by the rotation of the first rotating member (111) and the second rotating member (112), and they can be electrically connected. Additionally, as described later, the first rotating member (111) and the second rotating member (112) may have a structure in which they are separated into upper and lower parts and coupled by their combination.

[0068] As the first rotating member (111) and the second rotating member (112) have a structure in which they are arranged and joined adjacently in the longitudinal direction, the tile end of the first rotating member (111) and the end of the second rotating member (112) can come into contact and be rotated joined.

[0069] The tile end of the first rotating member (111) and the end of the second rotating member (112) may be provided as a connecting surface that faces each other and is joined, and a rotating fastening member (115) for rotating the first rotating member (111) and the second rotating member (112) may be provided.

[0070] The rotational fastening member (115) may include a guide groove (115a) and a guide projection (115b).

[0071] The guide groove (115a) may be provided on either the coupling surface of the first rotating member (111) or the coupling surface of the second rotating member (112). The guide groove (115a) may be formed as a groove that is inserted in a tube shape along the periphery of the seating hole of the other end of the first rotating member (111) or the first end of the second rotating member (112).

When the tile end of the first rotating member (111) and the end of the second rotating member (112) are engaged and joined, the guide projection (115b) is inserted into the guide groove (115a). Depending on the rotation of the first rotating member (111) and the second rotating member (112) in different directions, the guide projection (115b) may be guided and moved along the guide groove (115a).

[0074] The first rotating member (111) is positioned on the side of the first wire (11) and may be provided to cover the first wire (11) and the second wire (12). Specifically, the first rotating member (111) may be provided to receive the first wire (11) by penetrating from one end to the other end, and at the same time, receive the end of the second wire (12) in a predetermined inner direction from the other end toward the one end so as to be electrically connected.

[0083] At least one of the first upper and lower wire connecting members (111a, 111b) may be provided with a first locking projection (113) protruding toward the first seating hole (110a) (see FIG. 6). For example, the first locking projection (113) may be provided only on the first upper wire connecting member (111b) (see FIG. 6(b)), or alternatively, the first locking projection (113) may be provided only on the first lower wire connecting member (111a) (see FIG. 6(a)), or alternatively, the first locking projection (113) may be provided on both the first upper and lower wire connecting members (111a, 111b) (see FIG. 6(c)).

[0084] The first locking projection (113) may have a structure that engages with the ends of the first wire (11) and the second wire (12) housed in the first seating hole (110a), or penetrates and connects to the wires with or without insulation. As the first locking projection (113) engages with the ends of the first wire (11) and the second wire (12), the ends of the first wire (11) and the second wire (12) may rotate in the same direction as the rotation direction of the first rotating member (111) when the first rotating member (111) rotates.

[0085] The second rotating member (112) is rotatably coupled to the first rotating member (111) in the longitudinal direction adjacent to the first rotating member (111). The second rotating member (112) is positioned on the side of the second wire (12) and may be provided to cover the first wire (11) and the second wire (12).

[0087] The second rotating member (112) may include a second wire connecting member (112a, 112b) comprising a second upper wire connecting member (112b) and a second lower wire connecting member (112a), and a second rotating cover member (112c, 112d) comprising a second upper rotating cover member (112d) and a second lower rotating cover member (112c).

[0088] The second wire connecting member (112a, 112b) includes a second upper wire connecting member (112b) and a first lower wire connecting member (112a), wherein the second upper and lower wire connecting members (112b, 112a) may form a second seating hole (110b) for seating the end of the second wire (12) and the first wire (11). As described above, the second seating hole (110b) may be coupled with the first seating hole (110a) to form a seating hole (110a, 110b) for receiving the wires (11, 12). The second upper and lower wire connecting members (112b, 112a) may be provided with a conductive material that electrically connects the first wire (11) and the second wire (12).

[0089] The second upper and lower wire connecting members (112b, 112a) can be combined with each other to form a single second wire connecting member (112a, 112b). Additionally, a single wire connecting member is formed by engaging in the longitudinal direction with the first wire connecting member (111a, 111b) of the first rotating member (111) described above.

[0090] In the second upper and lower wire connecting members (112b, 112a), a plurality of protruding tips (116) may be provided so as to be adjacent to each other in the longitudinal direction of the wire connector housing (100). The tips (116) may be formed as protrusions protruding inward or as serrated edges with sharp surfaces. The tips (116) may be deformed to be adjacent to each other by the pressure of the wire cover part (120) described later. For example, the tips (116) having serrated edges may be provided to penetrate the sheathing of the wires (11, 12) located in the seating holes (110a, 110u) by pressure, thereby enabling an electrical connection through contact and pressure between the end of the first wire (11) and the end of the second wire (12).

[0091] At least one of the second upper and lower wire connecting members (112b, 112a) may be provided with a second locking projection (114) protruding toward the second seating hole (110b) (see FIG. 6). For example, the second locking projection (114) may be provided only on the second upper wire connecting member (112b) (see FIG. 6 (b)), or alternatively, the second locking projection (114) may be provided only on the second lower wire connecting member (see FIG. 6 (a)), or alternatively, the first locking projection (113) may be provided on both the second upper and lower wire connecting members (see FIG. 6 (c)).

[0092] The second locking projection (114) may have a structure that engages with the ends of the second wire (12) and the first wire (11) housed in the second seating hole (110b), or penetrates and connects to the wires with or without insulation. As the second locking projection (114) engages with the ends of the second wire (12) and the first wire (11), the ends of the second wire (12) and the first wire (11) may rotate in the same direction as the rotation direction of the second rotating member (112) when the second rotating member (112) rotates.

[0093] As described above, the first rotating member (111) is provided with a first upper and lower wire connecting member (111b, 111a), and the second rotating member (112) is provided with a second upper and lower wire connecting member (112b, 112a), and by combining these, an integrated wire connecting member (111a, 111b, 112a, 112b) is provided.

[0094] A seating hole (110a, 110b) is formed on the inner side of an integrated wire connecting member (111a, 111b, 112a, 112b), and a first wire (11) and a second wire (12) are positioned in the seating hole, so that the first wire (11) and the second wire (12) can be electrically connected by the wire connecting member.

[0095] A wire connecting member (111a, 111b, 112a, 112b) can be provided by combining a lower wire connecting member provided on a lower member (101) and an upper wire connecting member provided on an upper member (102) to form a single wire connecting member (111a, 111b, 112a, 112b).

[0096] The wire connecting members (111a, 111b, 112a, 112b) are each located on the inner surface of the first mounting hole (110a) and the second mounting hole (110b). The wire connecting members (111a, 111b, 112a, 112b) can receive pressure from the coupling of the outer cover member (121). As a result, the end of the first wire (11) and the end of the second wire (12), which are twisted by the first rotating member (111) and the second rotating member (112) and housed in the first mounting hole (110a) and the second mounting hole (110b), can make electrical contact and connection with the wire connecting members (111a, 111b, 112a, 112b) more firmly.

[0097] Additionally, the first rotating member (111) is provided with a first upper and lower rotating cover member (111d, 111c), and the second rotating member (112) is provided with a second upper and lower rotating cover member (112d, 112c). The first rotating cover member (111c, 111d) is formed by combining the first upper and lower rotating cover members (111d, 111c), and the second rotating cover member (112c, 112d) is formed by combining the second upper and lower rotating cover members (112d, 112c). In addition, as the first rotating cover member (111c, 111d) and the second rotating cover member (112c, 112d) are joined together in the longitudinal direction, one rotating cover member (111c, 111d, 112c, 112d) is provided.

[0098] The rotating cover member (111c, 111d, 112c, 112d) is provided between the wire cover part (120) described later and the wire connecting member (111a, 111b, 112a, 112b), and can be provided to implement the twisting of the ends of different wires (11, 12) as well as to cover the twisted different wires (11, 12) and apply a predetermined pressure to ensure the reliability of the electrical connection of the wires (11, 12).

[0099] The above-described wire connecting members (111a, 111b, 112a, 112b) can each be detachably coupled to the rotating cover members (111c, 111d, 112c, 112d).

[0100] A rotating cover member (111c, 111d, 112c, 112d) according to one embodiment of the present invention is provided between the wire cover part (120) described later and the wire connecting member (111a, 111b, 112a, 112b) and is provided to be elastically variable so as to implement elastic deformation of the wire connecting member (111a, 111b, 112a, 112b) coupled to the inside of the rotating cover member (111c, 111d, 112c, 112d). As the rotating cover member (111c, 111d, 112c, 112d) elastically varies, the wire connecting member (111a, 111b, 112a, 112b) can be pressed in close contact with the end of the first wire (11) and the end of the second wire (12) placed in the seating hole (110a, 110b).

[0101] FIG. 7 is a cross-sectional view in which a support member (117) is provided on a rotating connection part (110) in a wire connection device (10) according to one embodiment of the present invention.

[0102] FIG. 8 is a cross-sectional view showing a different shape of a support member (117) in a wire connection device (10) according to one embodiment of the present invention.

[0103] A support member (117) may be provided on the inner side of the rotating cover member (111c, 111d, 112c, 112d). The support member (117) may be provided along the perimeter of the first seating hole (110a) of the first rotating cover member (111c, 111d) and along the perimeter of the second seating hole (110b) of the second rotating cover member (112c, 112d), respectively.

[0104] For example, the support member (117) may be provided in a semicircular shape on the inner side of the first upper rotating cover member (111d), the first lower rotating cover member (111c), the second upper rotating cover member (112d), and the second lower rotating cover member (112c), respectively, and may be formed in a pipe shape by combining them.

[0105] The support member (117) is described as having a semicircular body, but is not limited thereto. For example, as shown in FIG. 5, the support member (117) may be provided with protrusions extending outward and inwardly from the semicircular body to increase the support force of the rotating cover member (111c, 111d, 112c, 112d).

[0106] Referring once again to FIGS. 1 to 6, which were previously referenced, the wire cover portion (120) is provided to surround the outer surface of the rotating connection portion (110) as described above, so as to cover the rotating connection portion (110) and prevent external foreign matter from entering the connected wires.

[0107] The wire cover portion (120) may include an outer cover member (121) and a sealing member (122).

[0108] The outer cover member (121) is provided to cover the first rotating member (111) and the second rotating member (112). The outer cover member (121) may have a single cover portion formed by combining a lower cover (121a) provided on the lower member (101) and an upper cover (121b) provided on the upper member (102).

[0109] A sealing member (122) may be provided between an outer cover member (121) and a rotational connection part (110) (a first rotational member (111) and a second rotational member (112)), specifically between the outer cover member (121) and the first and second upper and lower rotational cover members (111d, 111c, 112d, 112a). The sealing member (122) may be provided to close the space between the first and second upper and lower rotational cover members (111d, 111c, 112d, 112a) and the outer cover member (121) and to seal the seating holes (110a, 110b). A sealing member (122) can be provided to fill the space between the rotating connection part (110) and the outer cover member (121) to block foreign matter from entering the inside of the rotating connection part (110).

[0110] The sealing member (122) may include an upper sealing member (122b) of the upper member (102) and a lower sealing member (122a) of the lower member (101). The upper and lower sealing members (122b, 122a) may be provided as upper and lower connecting pouches (122d, 122c) filled with a liquid curing agent (122f). The upper and lower connecting pouches (122c) filled with the liquid curing agent (122f) may be installed in the sealing space (123) between the outer cover member (121) and the rotating connecting part (110). For example, the upper and lower connecting pockets (122c) can be mounted in the upper sealing space (123b) between the first and second upper rotating cover members (111d, 111c, 112d, 112c) and the upper cover (121b), and in the lower sealing space (123a) between the first and second lower outer cover members (121) and the lower cover (121a), respectively.

[0111] The upper and lower sealing members (122b, 122a) can be pressed between the outer cover member (121) and the rotary connection part (110) by coupling with the outer cover member (121) while positioned in the upper and lower sealing spaces (123b, 123a). As the upper and lower coupling pockets (122d, 122c) are ruptured by pressure in the upper and lower sealing spaces (123b, 123a), a liquid curing agent (122f) is filled into the space between the outer cover member (121) and the rotary connection part (110) and hardened, thereby sealing the spaces inside the wire connector housing (100), and thus preventing foreign matter from entering into the seating holes (110a, 110b).

[0112] The lower cover (121a) and the upper cover (121b) each form a contact surface to be in contact and closely coupled, and the contact surface may further be provided with a sealing portion (130) to achieve sealing of two different wires (11, 12) located between the wire connector housing (100) after electrical connection.

[0113] The contact portion (130) is provided on the respective contact surfaces of the upper cover (121b) and the lower cover (121a), and may be provided along the contact surfaces. For example, the contact portion (130) provided on the upper cover (121b) and the lower cover (121a) may have a shape of a connection form of '┏┑' and '┗┛' on the front and rear, respectively, based on the seating holes (110a, 110b) where the first wire (11) and the second wire (12) are placed.

[0114] A contact portion (130) according to one embodiment may include a contact projection (132) and a contact groove (131). The contact projection (132) may be provided on one of the contact surfaces of the lower cover (121a) or the upper cover (121b). The contact groove (131) may be provided on the other of the contact surfaces of the lower cover (121a) or the upper cover (121b). When the lower cover (121a) and the upper cover (121b) are combined, the contact projection (132) formed on one of the contact surfaces of the lower cover (121a) or the upper cover (121b) may be inserted into the contact groove (131) formed on the other of the contact surfaces of the lower cover (121a) or the upper cover (121b), thereby forming a structure that is tightly coupled and sealed.

[0115] Additionally, the end surface and the tile surface of the wire connector housing (100) serve as the end surface and the tile surface of the seating hole (110a, 110b), respectively, and the outer circumferences of the first wire (11) and the second wire (12) are respectively in close contact with the inner circumference of the end surface of the seating hole (110a, 110b) and the inner circumference of the tile surface of the seating hole (110a, 110b). In order to firmly secure the close contact between the end surface of the seating hole (110a, 110b) and the inner circumference of the tile surface and the wires (11, 12), an elastic pressure member (140) may be further provided around the inner circumference of the end surface of the seating hole (110a, 110b) and the tile surface.

[0116] The elastic pressure member (140) may be provided to protrude in the direction of the wire along the inner circumference of one end and the tile end of the seating hole (110a, 110b) of both ends of the wire connector housing (100).

[0117] An elastic pressure member (140) formed protruding in the direction of the first wire (11) along the inner circumference of one end of the wire connector housing (100), that is, one end of the seating hole (110a, 110b), can be in close contact with the outer circumference of one end of the first wire (11) and thus can be in close contact with the one end of the wire connector housing (100). Additionally, an elastic pressure member (140) formed protruding in the direction of the second wire (12) along the inner circumference of the one end of the wire connector housing (100), that is, one end of the seating hole (110a, 110b), can be in close contact with the outer circumference of one end of the second wire (12) and thus can be in close contact with the one end of the wire connector housing (100).

[0118] FIG. 9 is a schematic longitudinal cross-sectional view of a wire connection device (10) having a communication hole (150) in a wire connection device (10) according to one embodiment of the present invention.

[0119] Referring to FIG. 9 and again to FIG. 1 to FIG. 8, in one embodiment of the present invention, an upper and lower connecting pouches (122d, 122c) filled with a liquid curing agent (122f) are positioned in upper and lower sealing spaces (123b, 123a), respectively, and a structure is described as being sealed by bursting upon connection, but it is not limited thereto.

[0120] For example, when the wires (11, 12) twisted by the rotary connecting member (110) are combined, an outer cover member (121) can be combined to the outside of the rotary connecting member (110). When the outer cover member (121) covers the outside of the rotary connecting member (110), a sealing space (123) can be formed between the outer cover member (121) and the rotary connecting member (110). A structure can be formed in which a liquid curing agent (122f) is filled into this sealing space (123) and cured.

[0121] Specifically, a communication hole (150) communicating with the upper sealing space (123b) may be formed in the upper cover (121b). A liquid curing agent (122f) may flow into the upper sealing space (123b) and the lower sealing space (123a) through the communication hole (150), and may be cured after filling the upper and lower sealing spaces (123b, 123a) as well as the communication hole (150).

[0122] A liquid curing agent (122f) according to one embodiment of the present invention may be made of a material including a curable gel. The material of the liquid curing agent (122f) is not limited to a curable gel and may have fluidity and may fill both the lower sealing space (123a) and the upper sealing space (123b) through fluidity, and may be modified or altered as long as it is a material that can be cured over time or through a separate structure.

[0123] Additionally, the communication hole (150) is described as being formed as a single hole in the upper cover (121b) as an example, but is not limited thereto, and the location, shape, number, etc. of the communication hole (150) can be changed as many times as desired.

[0124] As described above, the upper sealing space (123b) and the lower sealing space (123a) each have a semicircular tunnel shape, and the structure in which the liquid curing agent (122f) fills the upper and lower sealing spaces (123b, 123a) having a semicircular tunnel shape was described as an example.

[0125] Although specific embodiments have been described in the detailed description of the present invention, it will be obvious to those skilled in the art that various modifications are possible within the scope of the invention. Explanation of the symbols
